Comment 3 for bug 773141

Matthew,
if
unity --reset
doesn't help
try
unity --replace

Workaround which helped here:
Disable automated plugin sorting.
Move 'wall' and 'static switcher' from right to left.
Move 'cube', 'rotate' and 'switcher' from left to right.
Enable automated plugin sorting. Done.
